BloomFilter is a probabilistic filter which SPV clients provide so that we can filter the transactions we send them.
Declared in <common/bloom.h>
class CBloomFilter;This allows for significantly more efficient transaction and block downloads.
Because bloom filters are probabilistic, a SPV node can increase the false- positive rate, making us send it transactions which aren't actually its, allowing clients to trade more bandwidth for more privacy by obfuscating which keys are controlled by them.
